"Isn't it sad to go to your grave without ever wondering why you were born? Who, with such a thought, would not spring from bed, eager to resume discovering the world and rejoicing to be part of it?"

Many adults are put off when youngsters pose scientific questions. Children ask why the sun is yellow, or what a dream is, or how deep you can dig a hole, or when is the world’s birthday, or why we have toes. Too many teachers and parents answer with irritation or ridicule, or quickly move on to something else. Why adults should pretend to omniscience before a five-year-old, I can’t for the life of me understand. What’s wrong with admitting that you don’t know? Children soon recognize that somehow this kind of question annoys many adults. A few more experiences like this, and another child has been lost to science.
There are many better responses. If we have an idea of the answer, we could try to explain. If we don’t, we could go to the encyclopedia or the library. Or we might say to the child: “I don’t know the answer. Maybe no one knows. Maybe when you grow up, you’ll be the first to find out.”

A brief history of microscopy by i-heart-histo
c2000 BC
The Chinese use water microscopes made of a lens and a water filled tube to better visualize smaller objects.
1590
Hans Jansen and his son Zacharias Jansen invent the compound microscope.
1609
Galileo Galilei develops a compound microscope with a convex and concave lens. Calling it the occhiolino - the little eye.
1625
The term ‘microscope’ is coined by Giovanni Faber of Bamberg, an anology with the word ‘telescope’
1665
Robert Hooke publishes Micrographia and coins the word ‘cell’ after his examination of cork bark.
1674
Anton van Leuwenhoek develops the compound microscope to optimize it for observing biological specimens.
1860s

1957
The Olympus DF Biological Microscope becomes the first microscope to feature an attached light source rather than a mirror that reflects light on the specimen.

Waiting hours for a cellphone to charge may become a thing of the past, thanks to an 18-year-old high-school student’s invention. She won a $50,000 prize Friday at an international science fair for creating an energy storage device that can be fully juiced in 20 to 30 seconds.
